  1. Fiber Optic Technology

  2. What are fiber optics? • Strands of optically pure glass as thin as human hair that carry digital information over long and short distances. • Arranged in bundles • Fiber Optic cables composed of three parts • Core – glass center where light travels. • Cladding – optical material surrounding the core that keeps the light in the core and reflects it back. • Buffer Coating – Coating that protects the fiber from damage and moisture.

  3. Applications of Fiber Optics • Communications • Verizon fios • AT&T U-Verse • Both companies bundle together TV and Internet • Internet speeds from 15 Mbps to 50 Mbps downstream with Verizon • Digital audio • TOSLINK originally by Toshiba • CD players, DVD players, even used in some gaming systems • Uses LED to send information

  4. Advantages • Less Expensive • Thinner • Can be drawn to smaller diameters than copper • Higher data capacity • Less degradation • No interference • Unlike copper, fiber does not suffer from electromagnetic interference • Low Power • Signals degrade less thus needing lower power transmitters can be used • Non-hazardous • Since there is no electricity there is no danger! • Flexible • Medical, mechanical, and plumbing

  5. Future Uses • Household • Faster internet download speeds • Better quality voice • Used more widely in home audio
